CodeIgniter & DBForge - Create Database and Tables

Question

I'm trying to write a script in CodeIgniter that will create a database and then will add tables to that newly created database along with various fields in to the new table.

So far I've got dbforge to create the new database but since I'm using the database library and have pre-set database connection values, when it goes to create a table, it puts it in the pre-selected database and not the one it just created.

In the database.php config file I have the following:

$db['default']['database'] = 'db1';

If I use the following command to create a new database:

$this->dbforge->create_database('db2');

'db2' will get created but then the following command puts the table in 'db1'.

$this->dbforge->create_table('table1');

I need 'table1' created in 'db2'. How do I get CI to select the newly created database ('db2') to create the table in the correct place, and then switch back to 'db1'?

I've looked at the following question which is similar to what I'm doing but I do not want to have to put any further connection entries in the database.php

Codeigniter showing error: No database selected

Any help appreciated!

EDIT - I should add that the create_database could have any name for the database name... This is a script to automatically create a database and the relevant tables where the DB name is pulled from a form.

Answer 1

$this->db->query('use db2');

$this->db->query('use DB1');

    if ($this->dbforge->create_database('my_db_test'))
{
    try{
      $current_database = "my_db_test";
      $this->db->database = $current_database;
     $this->db->close();
     $config['hostname'] = "localhost";

     $this->load->database($config);
    $fields = array(
                        'blog_id' => array(

                                          ),

    $this->dbforge->add_field($fields);

    }catch(Exception $e){
